...Wait, what? I feel kind of strawmanned.
Plenty of lawyers could argue that they're German citizens.
The point is that the issue is definitely
in doubt, because they represent twenty million cases of double identity. That may be easy for us to accept because we're used to science fiction full of clones or whatever, but it's not normal in the legal world.
The core of the German government's
hypothetical argument* would be
*Which realistically they'll only be making if someone tries to foist off all twenty million Wehrmacht soldiers on them all at once while totally ignoring the major consequences that would have for Germany...
Well yes, clearly they believe themselves to be German citizens of the 1939-45 time period. Clearly they speak the language, by all evidence have memories consistent with their claimed identity, and carry large amounts of military equipment that is supposedly from Germany of that era.
But at the same time, clearly all those men and weapons did not just vanish off the face of the Earth at any point. Some of those people are still alive. The rest of them are dead and buried. The weapons were destroyed in battle, scrapped after the war, or (occasionally) stored in museums.
So it is not simply the case that these are our citizens of 1939 who were somehow transported into our present of 2014. If that were so, then there would be plenty of historical evidence for those citizens having vanished. The course of the Second World War would certainly have been quite different if the entire Wehrmacht and Luftwaffe had suddenly vanished in mid-war!
So while it is clear that these men are in some sense 'German,' it is not clear that they were ever born, under the names they think are theirs, in Germany. We know what happened to the men who were born under those names... they're all dead or in nursing homes. These new doppelgangers cannot be the German nationals born in the 1920s and earlier as they claim, they must have originated from some other time or place unknown to us.
This is not to deny them basic human rights, simply to recognize that their legal status is unclear and the logistical challenges of taking care of them are formidable.
And frankly, they have a point.
Let me illustrate this with an absurd example. Suppose someone just arbitrarily created three hundred million clones of, say, Ronald Reagan circa 1950. This is done using whatever magic was involved in making this RAR happen; presumably if it happened once, it can happen again.
Does that mean the US is required to absorb these hundreds of millions of Ronald Reagan clones, and thus become a nation that consists of 25% normal American men, 25% normal American women, and 50% Ronald Reagan? Despite the disastrous problems of overpopulation, overcrowding, and the fact that 39-year-old black-and-white movie actors are now the single largest demographic in the entire world?
Such a situation would result in the rapid degeneration and collapse of the American economy and way of life, even with the best will in the world on the part of the three hundred million Ronald Reagan clones.
And
yes that scenario is deliberately absurd... but it's far from out of the question in light of what just happened in this RAR. If we say that Germany is required to accept all the Wehrmacht dopplegangers uncritically and instantaneously, simply because they
believe and appear to be German citizens circa 1939-45... that sets a precedent, one that really isn't to anyone's advantage.
Somehow, there is now a process by which some unknown force or entity can create hordes of duplicates of various persons, living or dead, and bring them into the modern world. We have to have some orderly means by which these duplicates are integrated into our society.
If there were only a few such duplicates, we could just say "OK, they have free citizenship in whatever country they think they're from, and all questions of their true origins are irrelevant." But nations will be literally unable to do that, out of a basic necessity to protect themselves from chaos, when dealing with tens of millions of duplicates. The alternative is very dangerous for the host nation, and not really to anyone's benefit.
